Last verified: December 2013
Women who are requesting pregnancy termination at 14-16 weeks, who would normally have osmotic dilator insertion the day before their procedure, would be asked if they wanted to participate. Participants would be randomized to two groups: first, dilator insertion as usual, or second, mifepristone taken the day before the procedure.

Condition Intervention
Abortion Drug: mifepristone 200 mg Device: osmotic dilator insertion

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Mifepristone vs. Laminaria Insertion for Cervical Preparation Prior to Surgical Abortion at 14-16 Weeks

Further study details as provided by Lynn Borgatta, Boston University:

Primary Outcome Measures:
  • Time for Completion of Procedure [ Time Frame: Performance and completion of the abortion procedure takes 10-20 minutes. The length of the procedure is measured. The procedure occurs approximately 24 hours after enrollment. ]
    Minutes, from the time of the start of the procedure (speculum insertion) to the conclusion of the procedure (speculum removal)

Secondary Outcome Measures:
  • Assessment of Ease of Procedure by Operator [ Time Frame: It is administered shortly after the primary outcome, which is one day after enrollment. The study is complete at that point. ]
    The operator for each procedure rated the ease of procedure on a categorical scale. The categories were collapsed into two: "easy or very easy" and "average or difficult".

  • Moderate or Severe Pain Overnight [ Time Frame: Overnight ]
    Women wer asked to rank their amount of pain on a catergorical scale. The outcome measure is the number of women experiencing moderate or severe pain overnight (after mifepristone or osmotic dilators, and before the abortions procedure)

Enrollment: 50
Study Start Date: October 2009
Study Completion Date: March 2011
Primary Completion Date: March 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: mifepristone
women in the mifepristone are would take mifepristone 200 mg for cervical preparation the day before their procedure, and not have dilators inserted. In this group, the sstandard procedure of osmotic dilator insertion is NOT performed.
Drug: mifepristone 200 mg
mifepristone would be given the day before the procedure
Active Comparator: Osmotic dilator insertion
Women assigned to this arm would have the standard procedure for cervical preparation, which is insertion of osmotic dilators the day before the abortion procedure
Device: osmotic dilator insertion
osmotic dilators (3-6) would be inserted as usual the day before the procedure
